We've had our dyson for about 5 years. I thought it was going to be the best vacuum ever...5 years down the road I HATE mine we have a dog and the belt is at the brush so my dogs hair always gets clumped around it. Then it makes a weird noise and I know it's time to take off the bottom and dig out the fist full if hair. Also when I empty it in the garbage there's a huge cloud of dust. They might have changed and helped the belt issue but the cloud of dust & dirt when emptying it is a common issue with bag less. I want to get a bag type of vacuum now.
